Title: Improvements in or relating to television pick-up tubes, and television transmittingapparatus incorporating the same
Inventor: THEILE RICHARD
IPC: H01J29/02
Filed: 1950-12-06
Abstract: 710,091. Television pick-up tubes; electron multipliers. PYE, Ltd. Nov. 21, 1951 [Dec. 6, 1950; Jan. 5, 1951; March 2, 1951; May 7, 1951], Nos. 29932/50, 408/51, 5130/51, and 10698/51. Class 39(1) A television pick-up tube of the storage type wherein the storage target is scanned by a high velocity beam and wherein strip-like electrodes extend along at least some of the edges of the target, the tube also including a source for producing a rain of low velocity electrons which flood the target, is characterized in that the two strip-like electrodes located along the edges of the target corresponding to the ends of line and frame scanning are biased positively with respect to the source of low-velocity electrons and with respect to the other strip-like electrodes, if any, so that they create an electrostatic field across the target which prevents the migration of secondary electrons and thus eliminates " flare ". The mosaic screen 11 may be surrounded by four electrodes 7, 7a, 7b and 7c, Fig. 5, electrodes 7 and 7a being biased positively and electrode 7b and 7c negatively; electrodes 7b and 7c may be omitted, Fig. 2 (not shown). The mosaic may be bombarded with a rain of slow electrons which may emanate from a thermionic source which may comprise filaments 27 connected between three rings 26, Fig. 4; alternatively a thermionic electrode may be provided in the form of a ring arranged near the envelope. In a modification, Fig. 1 (not shown), part of the coating 6 near the screen is photo-emissive and is illuminated by a ring of lamps arranged round the envelope. In another embodiment, Fig. 7, the edge of the photo-cathode 2a is illuminated by lamps and the resultant emission is accelerated on to a secondary emitting electrode 38, shown in Fig. 8, which preferably comprises a number of fins 39 arranged like turbine blades. An accelerator electrode 43 may be arranged in front of the electrode 38 to accelerate the secondary electrons on to the mosaic screen. In a modification of this arrangement, Fig. 6 (not shown), the electrode 38 is replaced by a secondary-emissive wall coating on the envelope in the same position as that shown for the electrode 38. In a further embodiment, Fig. 9, the tube is provided with an extension housing an electron gun comprising a cathode 46 and a diaphragm 47 connected to a wall coating 48; electrons from the gun impinge on a dynode 51 which emits secondary electrons, which follow the dotted path shown and pass through a coarse mesh 53 before impinging on a secondary emissive coating 52. The planar electrodes 7 of the previous Figures may be replaced by mesh electrodes 54, 55. Specification 688,904 is referred to.

Filed: 1972-06-28
Abstract: 1369936 Electro-chemical analysis DOW CHEMICAL CO 28 June 1972 30227/72 Addition to 1122121 Heading G1N The range of the process described in the Parent Specification 1122121 is extended downwards to determine the oxygen demand of aqueous dispersions containing relatively low amounts of combustible material. As heretofore the sample is injected into an oxygenated inert carrier gas which flows through a furnace housing a catalyst and the variation in oxygen content of the effluent is measured electro-chemically. In the present case the oxygen content of the carrier is 0À5-10 p.p.m. The sample is rendered substantially oxygen free by purging with inert gas or subjecting to a vacuum. The oxygen carrier may be commercial nitrogen treated with pyrogallol or activated sodium sulphite to reduce the oxygen to a suitable level.

Patent GB-306358-A (GB)
Abstract: 306,358. Fraser, J., and British Petroleum Co., Ltd. July 14, 1928. Single - acting bucket pumps; measuring - devices; sealing-devices.- In a bucket pump for delivering measured quantities of liquids, the piston rod 12 carries a disc 17 which closes the delivery port 9 when the piston 2 stops, and so prevents the kinetic energy of the liquid from opening the valve 4 in the piston. The pressure set up in the cylinder 1 by the kinetic energy condenses any vapour in the cylinder or suction line. The disc 17 carries a conical member 18 loosely embracing the piston rod and adapted to close the port 9 gradually before the disc seats. The return stroke of the piston is limited by an adjustable stop 11 on the piston rod. When the piston is moved to its inner position it engages the spring-pressed piston rod 26 of a dash-pot on the suction valve and keeps the valve closed against leakage. A totalisor may be operated by a spring controlled spindle 28 on the shaft 7 of the pinion 6 which operates the piston 2.

Filed: 1973-06-27
Abstract: 1410875 FET logic circuits HITACHI Ltd 27 June 1973 [28 June 1972] 30655/73 Heading H3T A static flip-flop circuit for use as a memory store comprises first, second and third inverters including FETs Q5, Q4' Q11 with respective resistive loads Q1' Q2, Q10' transfer gate FETs Q3' Q19 for respectively coupling the output of first inverter to the gate of Q4 and for deriving an output signal in response to clock pulses #1, #2' a series connection of the drain source paths of an input transistor Q6 and a write control transistor Q7 connected across the drain source path of Q5, a further write control transistor Q8 having its drain source path connected across that of Q4, a direct feed-back connection between an output of the second inverter with the gate of Q5 and a connection between the gates of Q4, Q11 to enable Q11 to store the same charge as Q4. In operation, when the write control signal X is at "O" level, FETs Q7, Q8 are turned on and Q5 is turned off. When the next clock pulse #1 reaches "O" level, a new bit of information corresponding to the logical level of the input signal Vin is written in via FETs Q6, Q3 into the storage transistors Q4' Q11. Subsequently signal X attains a level of "1" and transistors Q7' Q8 are turned off and Q5 turned on so that the previous bit of information is rewritten into Q4, Q11 whenever #1 pulse becomes "0" to render Q3 conducting. Information written in is read off via Q19 whenever clock pulses #2 reach "O" level. If, when the write control signal X again attains "O" level, the input Vin has a different level, the new bit of information is written in. The load transistors Q1, Q2' Q10 may be biased by a fixed D.C. potential instead of the clock pulses #1, #2 or alternatively they may be replaced by other resistive loads. The arrangement shown may be modified by connecting a reset control FET in series with Q8 while a set signal is applied to Q6.

Filed: 1946-10-16
Abstract: 618,038. Sifting-apparatus. STRAIN. G. H. Oct. 16, 1946, No. 30819. [Class 117] In screening apparatus comprising a rigid member or primary mass mounted on springs and subjected to substantially rectilinear vibrations, and a screening compartment or secondary mass adapted to vibrate in accordance with the movements of the primary mass, buffer springs, interposed between the two vibrating masses, serve to determine the deceleration and acceleration of the secondary mass as it approaches or recedes from the primary mass. As shown, the primary mass 3 is connected to the stationary framework 12 by leaf springs 4 and is reciprocated vertically by connecting rods 2 from an eccentric shaft 1. The screening compartment 6 is connected to the framework 12 by leaf springs 9 and tension springs 11, and to the primary mass 3 by further tension springs 10, all connected to the side members 7 of the compartment 6. Buffer springs 5 are adjustably secured to the mass 3, and may be moved into or out of contact with the side-members 7 of compartment 6. When all the buffer springs are, at all times of working, in contact with the compartment 6, the motion of the latter is simple harmonic of an amplitude and frequency determined by all the springs 5, 9, 10, 11. The buffer springs 5 may be set to part company with the compartment 6, either all at once or in succession, on the downstroke, and to meet it again on the upstroke, the distance or period of deceleration being determined by the stiffness of the buffer springs. With the arrangement shown the whole machine must be tilted to cause the material to travel along the surface 8. In a modication the framework 12 and compartment 6 are horizontal, but the primary mass 3 and the springs are arranged at an angle so that the screening impulses are inclined to the screening surface 8. In a modification the framework 3 is divided into two halves, with two sets of leaf springs 4 and two sets of buffer springs 5. Specification 493,216 is referred to.
